To all whom it may concem:

Be it known that I, TONJES AUeUs'r CARL BOTH, a citizen of the United States, and a. resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanical Movements and Electric-Light Sockets, (Case U,.) of which the followmg is a specification, taken in connection with a switch mechanism in an electric light socket, to which it is particularly adapted owing to its simplicity, the few parts, and

the small space occupied by them. When so used it makes a quick make and a quick break of the electric current, without arcing, upon the rotation of the driving member in either direction.

Among other advantages, my mechanical movement permits the socket to be formed smaller and stronger for the opening in which the mechanical movement is mounted need not be so large as for other switch mechanism. In illustrating my invention I have, therefore, by way of example, shown it as a switch mechanism in an electric light socket, but it is to be understood, of course,

that the mechanical movement is not to be limited to this use. i

In the accompanying-drawings showing illustrative embodiments of my invention and in which the same reference numerals refer to similar parts in the several figures,--Figure 1 is a longitudinal vertical sectionthrough my mechanical movement mounted in an electric light socket, the insulating member of the socket being shown in side elevation; Fig. 2 is a longitudinal vertical section substantially on the line 22 of Fig. 1, looking in the direction of the arintermediate or hill and valley member shown in Fig. 5; Fig. 7 is a plan view of the blank from which I preferably form the preferred form of resilientdriven member;

ig. 8 is a side elevation of, the resilient driven member formed from the blank shown in Fig. 7.

In the illustrative embodiment of my in vention shown in the drawing, 1 is an electric light socket formed of two comp1ementary insulating members 2 and 3. having meeting surfaces 4, 4. i i

The driving member 5 is provided with cranks 6, 6'upon which are mounted links 7, 7 one link being mounted upon each era out of stamped metal and, as shown in Fig. 4, comprises. hollow head 8 having a slot 9 for the reception of the cranks 6 or 7, as the case may be, and are further provided with legs 40, 40 having bent in portions 10, 10, Fig. 4. -Upon the le s 40 I mount my inter-. mediate or movable inn and valley member 11 which is preferably formed out of a single stamping, its ends being cut at 12, 12 to form the kickers or accelerators 13, 13, the valleys 14, 14 and the arms 15, 15. By way of example I haveshown the kickers or accelerators bent up in one direction, and the arms 15 in the opposite direction, Fig. 6. These arms 15, 15 cooperate with the bent in portions 10 of the links 7 leaving the bent up portions, kickers or accelerators 13 free to cotiperat with the end 12 of the resilient driven member 16.

My preferred form of resilient driven member is formed from a stamping. A blank 17, Fig. 7, is stamped from sheet metal and provided with strengthening ribs 18, 18 which are preferably. rolled, stamped or otherwise formed. "I also preferably provide the blank with offsets 19, 19, one end 20 of the blank being preferably slotted by the slot- 21, Fig. 7. When this blank 17 is Patented June 11, 191 2.

These links are preferably formed bentback upon itself, the resilient drivem screw 38, is secured to the insulating member member 16 is formed, on end being further preferablv bent back upon itself o make an engaging arm 22, Figs. 1 and 8, which is adapted to be received in the valleys 14, 14 in the intermediate or movable hill and val.- ley member 11, and to cotiperate with the ledge 23 and with the boot, kicker or accelerator 13 in a manner to be hereinafter described? The two coiiperating insulating members 2, 3 are provided with guide grooves 24, 24 within which slide the lmks 7, 7. By rotating the driving member 5 in either direction, the cranks 6, 6 will reciprocate the links 7, within their grooves 24, carryin with them the intermediate or movable hill and valley member 11. If the drivin member 5 is rotated in either direction om the position shown in Fig. 1, the elevated link 7 will cause the endof the plate 11 with which it cooperates, to move down and cause the two ends of the resilient driven member 16 to approach each other until such time as the accelerator or kicker 13 will crowd or force the end 22 out of the valley 14 and over the ledge 23 of the member 11 when thespring or resilient driven member 16 will'instantly snap over with a quick and positive sna fi'om the position shown in Fig. 1 to the le t until the entire driven resilient member 16 has been moved to the left audits end 22 has been received in the other valley 14 of the intermediate member 11. This movement is instantaneous once the end 22 is released from the particular valley 14 with which it happens to be in en agement. The end of the member 11 which is now shown depressed will then be elevated. By then rotating the driving member 5, in either direction, the resilient driven member 16 will be caused to snap back into the position shown in Fig. 1. I have shown this me- -chanical movement as a switch mechanism in an electric light socket in which the screw shell 26 has a contact 27, Figs. 1 and 2, which extends within the opening 28 between the insulating members 2 and 3 and spaced from the contact 29 carried by the binding post 30. This s ace is bridged by the resilient driven mem er 16 when the current is to be passed through the consuming device. The electric current will be made or broken with a quick and positive snap, without arcing, so that both a quick make and a quick break will be made upon the rotation of the driving member 5-in either direction. The screw shell 26 is cut away at 31 so that the center contact 32, which is preferably an arm of the binding plate 33, may be inserted. This binding plate 33 ,is secured to the insulating member 2 by means of the screw 34. The binding screw 35 is carried by the binding plate 36.

The binding post 37 carrying the binding 3 by means of the locking screw 39 which serves at-the same time to secure the two insulating members 2 and 3 together.

It is, of course, to be understood that while I preferably use one kicker or accelerator with each groove" or valley, I may in all forms of my invention omit such accelerators, or use onl one.

Hav ng thus escrlbed this invention in connection with an illustrative embodiment thereof to the details of which I do not desire to be limited, what is claimed as new and what it is desired to secure by Letters Patent is set forth in the appended claims.
